Addition & Subtraction
Same Signs: Add & Keep Sign
Add the absolute values together and keep the common sign.
3 + 5 = 8
-3 + (-5) = -8
-3 + (-5) = -8
Different Signs: Subtract & Keep Larger
Subtract the smaller number from the larger number. Take the sign of the number with the larger absolute value.
-7 + 4 = -3 (7 is bigger, answer is negative)
8 + (-2) = 6 (8 is bigger, answer is positive)
8 + (-2) = 6 (8 is bigger, answer is positive)
Subtracting a Negative?
Two minuses side-by-side turn into a positive! (Add the opposite)

Multiplication & Division
Same Signs = Positive Answer
Multiplying or dividing two numbers with the SAME sign always gives a POSITIVE result.
(+4) × (+3) = +12
(-4) × (-3) = +12
(-10) ÷ (-2) = +5
(-4) × (-3) = +12
(-10) ÷ (-2) = +5
Different Signs = Negative Answer
Multiplying or dividing two numbers with DIFFERENT signs always gives a NEGATIVE result.
(+4) × (-3) = -12
(-4) × (+3) = -12
(-10) ÷ (+2) = -5
(-4) × (+3) = -12
(-10) ÷ (+2) = -5
